Cao Chong, the protagonist of the story Cao Chong Called the Elephant , is particularly loved by Ca

Because Cao Chong is very smart, likes to learn, and likes to use his brain, Cao Cao likes him very much.

Because this is his smartest son, who knows everything, loves to learn very much.

Because Cao Chong is particularly smart and talented, which Cao Cao's other sons do not have.

Because they are smart and brave, they are liked, but today's children don't have the courage and intelligence of others.

Because Cao Chong is Cao Cao's most beloved son, he is the favorite of Cao Cao, who is smart and capable.

Because this child is so likable, there is no one who doesn't love it, smart and educated.

Of course my children like it, and they're very smart.

Cao Chong was only seven years old when he said that his intelligence was different from that of mortals.

Cao Chong is looking for someone who likes to use his brain, and adults don't know what to do.

When Cao Chong was five or six years old, his knowledge and judgment skills were like those of an adult. Once, Sun Quan sent a giant elephant, and Cao Cao wanted to know the weight of the elephant and asked his subordinates about it, but none of them could tell how to weigh it. Cao Chong said

Put the elephant on the big boat, mark the place where the water has reached, and then let the boat load other things, weigh these things, and you will know by comparison. "Cao Cao was very happy to hear this, and immediately did so.

The story of "Cao Chong weighs the elephant" has been passed down to this day, and the most famous is the method used by Cao Chong, in which he replaced the elephant on the boat with a stone, while other conditions remained the same, so that the effect (the depth of the hull immersed in the water) was the same for both times, so that the weight of the elephant was equal to the weight of the stone. This method is called the "equivalent substitution method".

praised Cao Chong's extraordinary wisdom when he was young. Age is not about age, the key is to be good at observing things, use your brains to find a way, and children can also do big things.

？？？I don't know one.

！！Good or bad.

Tell the story of a little child who weighs an elephant. The child's name was Cao Chong.

Cao Chong's father, Cao Cao, was a big official, and a foreigner gave him an elephant, and he wanted to know how much the elephant weighed, so he asked his subordinates to find a way to weigh the elephant.

It's a hard thing to do. Elephants are the largest animals on land. How do you call it? There weren't such big scales, and people didn't have that much strength to lift elephants up. They are all worried about the elephant, and no one can think of a way to weigh the elephant.

At this moment, a little child ran out, stood in front of the adults and said, "I have a way, I have a way!" When they looked at it, it turned out to be Cao Cao's youngest son, Cao Chong, who didn't say anything in his mouth, but thought in his heart: Hmph! Adults can't think of a way, one.

Five-year-old children, what can be done!

But don't look down on children, this little Cao Chong has a way. He couldn't even think of a way for adults to think of for a while. His father said, "You can tell me quickly." ”

Cao Chong said, "I will show you, and you will understand." ”

He had the elephant led, and followed him to the river. His father, as well as those a**s, wanted to see how he was called, and followed him to the river. There happened to be an empty boat by the river, and Cao Chong said, "Lead the elephant to the boat." ”

Daxiang got on the boat, and the ship sank a little. Cao Chong said: "Qi water surface on the boat gang to draw a mark. After the mark was marked, Cao Chong asked someone to bring the elephant ashore. At this time the big ship was empty, and the big ship took some prisoners up.

Next, Cao Chong asked someone to pick up stones, load them on the big ship, pick up load after load, and the big ship slowly sank again.

Alright, alright! Cao Chong saw that the markings on the boat gang were on the water, so he asked people to pick up the stones and carry them off the boat. At this time, everyone understood: the stone was loaded on the ship and the elephant was loaded on the ship, and the ship sank to the same mark, and it was seen, the stone.

It weighs the same as an elephant; Weigh all the stones and add them up, and you get the weight of an elephant.

Everyone said that this method seemed simple, but if Cao Chong hadn't done it for everyone to see, adults really wouldn't have figured it out. Cao Chong is so smart!

The buoyant force experienced by an object in the water is equal to the gravitational force expelled from the water, which is the Archimedes' principle.

Cao Chong placed the elephant on the boat, and the gravity of the water in the boat was equal to the gravity of the elephant plus the boat. Then the stones are put in, and the gravity of the stone and the boat is equal to the gravity of the elephant and the boat, so that the gravity of the elephant and the boat is b, and the gravity of the stone is c, because they are both floating in edema, and the gravity is equal to the buoyancy of the elephant. There is a+b=c+b, so c=a, the mass of the stone is equal to that of the elephant!

The principle has Archimedes' principle, the principle of equal substitution!
